Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine the speed of an object?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What does a graph of a linear relationship look like?

Back

A linear relationship is represented by a straight line on a graph.

Front

What is the purpose of a table in representing relationships between variables?

Back

A table organizes data to show how one variable affects another, making it easier to analyze relationships.

Front

How can you find the distance traveled by an object moving at a constant speed?

Back

Distance can be found using the formula Distance = Speed × Time.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change between the two variables represented in the equation.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

How do you interpret a graph showing a direct variation?

Back

In a direct variation graph, as one variable increases, the other variable also increases, and the graph passes through the origin.

Front

What is the formula for calculating the cost based on time rented?

Back

Cost = Rate × Time, where Rate is the cost per unit of time.

Front

What is a variable in mathematics?

Back

A variable is a symbol used to represent an unknown value in mathematical expressions or equations.
